Microsoft has just responded to Google's move regarding Exchange ActiveSync. Sadly, instead of addressing the very real problems consumers are about to face, Microsoft starts talking about switching to Outlook.com.

They're also very slow to respond to changes in the market, compared to their competitors. Even if they start today on adding support for those standards, I'd not expect them to be shipping that support for at least a year, probably more - it'll come whenever their next major release occurs.
